Default lunati .660 ls1 spring package

Anyone ran these springs with good or bad luck? Any horror stories or compliments or anything about them would be great. Just ordered some and want to make sure there's not like a huge failure rate or anything crazy. I understand they're cheap and you get what you pay for but for a mild hydraulic roller I'd imagine they'll do just fine as long as there isn't any metallurgical problems w the wire they're made from or anything crazy I'm sure there would be a recall by now but I know its a fairly new spring package and want to make sure its not another comp 918 deal. (I know comp has long since rectified that issue but just saying) any insight is greatly appreciated. Sorry for the rant lol let's hear about them...

Thank you sir. Would you mind elaborating on your 7500rpm setup? I'm gonna run these on my ls6 cts-v. I'd like to turn it that high but my cam and stock int mani will make power that high but I know my heads will. Was hoping to turn it at least 72 but well see

I have a set the installed at about 1.825 on my stock 241s. CB was at 1.0 I have my note st the shop on them. I actually have 2 sets, a older set the springs were gold, and had I think blue seals. And a set form a few months ago. The swere polished looking, with black seals. The newer set is a stiffer spring.
I ended up using a different Ti retainer that installed them to about 1.790 1.800 on my stock 241s, and shimmed them. But check out the seal when you do that, how far it will install, and where it will hit. Oh and the kits retainer and lock was 21g and the Ti set I went to was 16g. I got notes on all this, I need to get my older gold set on the tester and get the numbers. took it to 7150rpms on stock everything. (LS1 heads/valves,rockers, .80 wall 5/16 4130 Prods... and I think there were floating, check my 441whp cam only dyno post fpr the chart. Had some marks on the spring seat/loccaters, and the locks were stuck getting them off. havnt had time to look into the gold set, what specs there at right now. Non were sagging, or tilted or anything really bad looking after 700miles
